Question about Prego ASF

I just got a breeding colony about a month ago now and I finally noticed that one is pregnant. Yesterday was the first day that you could visually tell that she had a bulge in her belly when you hold her upside down from the base of her tail.
I was just wondering if anyone has any idea as to how long it usually takes for them to pop once you notice a bit of a belly??

Any pics?

I have class here in a few but I will get pics up as soon as I get back

Here is a pic of her belly

And this is one of the other girls belly that doesn't appear prego

i noticed dark wood shaving in your bedding,what are you using?

it looks like you'll have a litter in a week or so.have fun!

Premier Pet
Scent-Free Aspen Bedding.
I got it from PetSmart. I also have some little apple tree branches in there that they seem to really like.

If you look really close you can see the little pieces that came off a pringle can as well. They go nuts over pringle cans! ha I give them something new every week so that they keep their minds off trying to escape. I haven't had any chewing at the tub yet. (Knock on wood):)

When they bulge and waddle, youve got a week or less till they drop. When they just bulge, about a week or so.

25-28 days in between litters btw, so once this first one drops you should be able to predict the next one.

Awesome! How many litters does an average female have per year? If heat is maintained throughout the year, will they continue to have a litter every month?

Just got home from work and this is what I found:banana:
